Hypothetical Sibset Theme Idea (Tacky or Somewhat Subtle?)

Last night I realized that using color names for a large sibling group might be really cool. I think there is enough variety in names that describe color that one might be able to pull it off without being too tacky.

I generally find themes a bit tacky, I'm afraid, unless they're so subtle it's more of a family secret thing (like the meanings are related, or the stories from which they come are related). I would name a sibset in a story I was writing a theme like this, or I would use names like this for middles, but not real life siblings' first names.

It really depends.
This is very helpful,I know lol
I think it depends on the theme. Movie/book characters wouldn't be to bad, considering there's a broad spectrum that can be covered (as long as it's not all in one movie/book)
I despise themes in which the sibset begin with all the same letter.
I don't like the color theme idea at all. It's not very subtle in my opinion, especially when you browse through the paint section at the hardware store.
